Ngā Tohu Hua

He mata parau kaha tēnei hua (e mōhiotia ana ko te mata whakawātea whenua) i hangaia mō te mahi ahuwhenua. Hei taputapu mahi matua mō ngā parau hurihuri me ngā tarakihana, e whakamahia ana mō te whakaora whenua pāmu, te whakaora whenua koraha, te tapahi tarutaru, me ngā mahi tango tarutaru. He mea hanga motuhake kia taea ai te aro atu ki ngā taiao oneone uaua me te mārō, ā, he mea pai mō te whakapai ake i te hanganga oneone me te whakarei ake i te whai huatanga o te parau.

Kei roto i tēnei hua ngā mātāpono o te miihini me te āhuahanga i roto i tōna hoahoa, ko te nuinga o ngā āhua hanganga he āhua-C me te āhua-L. He tika te mata, ā, he tino pakari. E rua ngā wāhanga o te tinana o te mata: te kakau me te pito o te mata.

Kakau o te Mata: E rua ngā kōhao whakatika tika hei hono haumaru ki ngā mīhini ahuwhenua, kia mau tonu ai te pumau, ā, kāore e nekeneke i raro i ngā kawenga taumaha.

Pane Mata: Ka whakamahia he tukanga piko āhua-pewa, tae atu ki ngā mata tapahi-mua me ngā mata tapahi-taha. Ko tōna piko ahurei (tata ki te 119°-120°) me te tautuhinga teitei ka whakaiti i te ātete i te tapahi ki te oneone, ka hua ake he pakaru oneone pai ake, he hohonu mahi ōrite hoki.

Hei whakatutuki i ngā hiahia mō te ātete kaha ki te pānga me te ātete ki te kakahu, he mea hanga te tinana o te mata mai i ngā rauemi maitai puna pakari-teitei pērā i te 60Si2Mn, 60Si2MnA, me te 28MnSiB.

I muri i te maimoatanga wera pakari (te whakawhiti āhua martensitic), ka whakahaerehia te pakeketanga whānui o te hua i waenga i te HRC 42 me te 48, kia kore ai te mata e whati ngāwari, e pōuri rānei i raro i te pānga kaha. Hei tāpiri, ko ētahi tauira he paninga koranu rewa-wera i runga i te mata o te mata, e kore e whakarei ake i te ātete kakahu engari he mahi "whakakoi-ake" anō hoki—arā, ka pupuri i te koi o te mata o te mata i te wā e kakahuria ana, ka whakaiti i te whakapaunga hiko me te whakatutuki i te penapena pūngao.

He whānui te hototahi o tēnei hua ki ngā tarakihana nunui me ngā tarakihana rahi-waenga, ā, he tino pai mō te whakaora whenua, te tapahi tarutaru tawhito, me te keri i ngā papa whenua mania, whenua maroke, me ngā pari ngawari. Ka taea e ia te wawahi i ngā paparanga oneone kua kikī, te whakanui ake i te pūngao o te oneone, me te whakarato i te taiao whakatō purapura kia mahorahora, kia manawa hoki mō te whakato hua i muri mai.
